FEATURES / CHARACTERISTICS

  1. This isolation valve features a wetted flow path constructed entirely of corrosion-resistant materials. Its newly developed structure eliminates the need for a diaphragm, significantly reducing both pumping volume and internal volume. The low pumping volume minimizes errors and variation during micro-volume dispensing, making it ideal for high-precision dispensing applications.
  2. The internal volume has been reduced by approximately 60% compared with our conventional equivalent models.
  3. With a slim 7 mm width, this valve enables high-density manifold mounting, significantly reducing both flow path length between ports and installation space. It is also suitable for 8-nozzle configurations for 96-well plate dispensing.
  4. Its structure is designed to minimize the influence of fluid pressure, allowing both IN and OUT ports to withstand pressures up to 200 kPa equally. This makes it suitable for applications involving high back pressure.
